The amount of time it takes to recall a preset is determined by several different variables, like the amount of blocks included in that preset, the type of blocks, whether you're recalling the entirety of the block or just some of it's parameters; whether the system is a single or multi-device one, whether the system is actually doing something else at the time, like receiving information via the serial port, or updating a busy daVinci panel, etc, etc, etc.

In any case, if you're trying to speed up the recall time, a preset changing fewer parameters will usually be recalled faster than one with more blocks in it.

Out of curiosity, how bad is the delay you're experiencing? Is your file too busy, or do the presets include many DSP blocks? If your delay really gets in the way, feel free to send the file over to support and we'll be happy to have a look at it.

I hope this helps
